New Relic Ruby security agent

The New Relic security agent for Ruby is in public preview and is not generally available. This module enables instrumentation of Ruby applications for interactive application security analysis (IAST) and exposes exploitable vulnerabilities.

Note: The IAST capability should only be used in pre-production environments and never in production.

Installation

The software is meant to be used along with the New Relic Ruby Agent. You can see New Relic ruby agent install instructions here.

With Bundler

For using with Bundler, add the Ruby agent to your project's Gemfile.

gem 'newrelic_security', require: false

and run bundle install to activate the new gem.

Without Bundler

If you are not using Bundler, install the gem with:

gem install newrelic_security

Getting Started

The newrelic_security must be explicitly enabled in order to perform IAST analysis of the application. In the newrelic.yml, set the following parameters:

 security:
   agent:
     enabled: true
   enabled: true
